BACKGROUND

Signal boosters and repeaters can be used to increase the quality of wireless communication between a wireless device and a wireless communication access point, such as a cell tower. Signal boosters can improve the quality of the wireless communication by amplifying, filtering, and/or applying other processing techniques to uplink and downlink signals communicated between the wireless device and the wireless communication access point.

As an example, the signal booster can receive, via an antenna, downlink signals from the wireless communication access point. The signal booster can amplify the downlink signal and then provide an amplified downlink signal to the wireless device. In other words, the signal booster can act as a relay between the wireless device and the wireless communication access point. As a result, the wireless device can receive a stronger signal from the wireless communication access point. Similarly, uplink signals from the wireless device (e.g., telephone calls and other data) can be directed to the signal booster. The signal booster can amplify the uplink signals before communicating, via an antenna, the uplink signals to the wireless communication access point.

Example Embodiments

An initial overview of technology embodiments is provided below and then specific technology embodiments are described in further detail later. This initial summary is intended to aid readers in understanding the technology more quickly but is not intended to identify key features or essential features of the technology nor is it intended to limit the scope of the claimed subject matter.

FIG. 1 illustrates an exemplary signal booster 120 in communication with a wireless device 110 and a base station 130. The signal booster 120 can be referred to as a repeater. A repeater can be an electronic device used to amplify (or boost) signals. The signal booster 120 (also referred to as a cellular signal amplifier) can improve the quality of wireless communication by amplifying, filtering, and/or applying other processing techniques via a signal amplifier 122 to uplink signals communicated from the wireless device 110 to the base station 130 and/or downlink signals communicated from the base station 130 to the wireless device 110. In other words, the signal booster 120 can amplify or boost uplink signals and/or downlink signals bi-directionally. In one example, the signal booster 120 can be at a fixed location, such as in a home or office. Alternatively, the signal booster 120 can be attached to a mobile object, such as a vehicle or a wireless device 110.

In one configuration, the signal booster 120 can include an integrated device antenna 124 (e.g., an inside antenna or a coupling antenna) and an integrated node antenna 126 (e.g., an outside antenna). The integrated node antenna 126 can receive the downlink signal from the base station 130. The downlink signal can be provided to the signal amplifier 122 via a second coaxial cable 127 or other type of radio frequency connection operable to communicate radio frequency signals. The signal amplifier 122 can include one or more cellular signal amplifiers for amplification and filtering. The downlink signal that has been amplified and filtered can be provided to the integrated device antenna 124 via a first coaxial cable 125 or other type of radio frequency connection operable to communicate radio frequency signals. The integrated device antenna 124 can wirelessly communicate the downlink signal that has been amplified and filtered to the wireless device 110.

Similarly, the integrated device antenna 124 can receive an uplink signal from the wireless device 110. The uplink signal can be provided to the signal amplifier 122 via the first coaxial cable 125 or other type of radio frequency connection operable to communicate radio frequency signals. The signal amplifier 122 can include one or more cellular signal amplifiers for amplification and filtering. The uplink signal that has been amplified and filtered can be provided to the integrated node antenna 126 via the second coaxial cable 127 or other type of radio frequency connection operable to communicate radio frequency signals. The integrated device antenna 126 can communicate the uplink signal that has been amplified and filtered to the base station 130.

In one example, the signal booster 120 can filter the uplink and downlink signals using any suitable analog or digital filtering technology including, but not limited to, surface acoustic wave (SAW) filters, bulk acoustic wave (BAW) filters, film bulk acoustic resonator (FBAR) filters, ceramic filters, waveguide filters or low-temperature co-fired ceramic (LTCC) filters.

In one example, the signal booster 120 can send uplink signals to a node and/or receive downlink signals from the node. The node can comprise a wireless wide area network (WWAN) access point (AP), a base station (BS), an evolved Node B (eNB), a baseband unit (BBU), a remote radio head (RRH), a remote radio equipment (RRE), a relay station (RS), a radio equipment (RE), a remote radio unit (RRU), a central processing module (CPM), or another type of WWAN access point.

In one configuration, the signal booster 120 used to amplify the uplink and/or a downlink signal is a handheld booster. The handheld booster can be implemented in a sleeve of the wireless device 110. The wireless device sleeve can be attached to the wireless device 110, but can be removed as needed. In this configuration, the signal booster 120 can automatically power down or cease amplification when the wireless device 110 approaches a particular base station. In other words, the signal booster 120 can determine to stop performing signal amplification when the quality of uplink and/or downlink signals is above a defined threshold based on a location of the wireless device 110 in relation to the base station 130.

In one example, the signal booster 120 can include a battery to provide power to various components, such as the signal amplifier 122, the integrated device antenna 124 and the integrated node antenna 126. The battery can also power the wireless device 110 (e.g., phone or tablet). Alternatively, the signal booster 120 can receive power from the wireless device 110.

In one configuration, the signal booster 120 can be a Federal Communications Commission (FCC)-compatible consumer signal booster. As a non-limiting example, the signal booster 120 can be compatible with FCC Part 20 or 47 Code of Federal Regulations (C.F.R.) Part 20.21 (Mar. 21, 2013). In addition, the signal booster 120 can operate on the frequencies used for the provision of subscriber-based services under parts 22 (Cellular), 24 (Broadband PCS), 27 (AWS-1, 700 MHz Lower A-E Blocks, and 700 MHz Upper C Block), and 90 (Specialized Mobile Radio) of 47 C.F.R. The signal booster 120 can be configured to automatically self-monitor its operation to ensure compliance with applicable noise and gain limits. The signal booster 120 can either self-correct or shut down automatically if the signal booster's operations violate the regulations defined in FCC Part 20.21.

In one configuration, the signal booster 120 can improve the wireless connection between the wireless device 110 and the base station 130 (e.g., cell tower) or another type of wireless wide area network (WWAN) access point (AP). The signal booster 120 can boost signals for cellular standards, such as the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) Release 8, 9, 10, 11, 12, or 13 standards or Institute of Electronics and Electrical Engineers (IEEE) 802.16. In one configuration, the signal booster 120 can boost signals for 3GPP LTE Release 13.0.0 (March 2016) or other desired releases. The signal booster 120 can boost signals from the 3GPP Technical Specification 36.101 (Release 12 Jun. 2015) bands or LTE frequency bands. For example, the signal booster 120 can boost signals from the LTE frequency bands: 2, 4, 5, 12, 13, 17, and 25. In addition, the signal booster 120 can boost selected frequency bands based on the country or region in which the signal booster is used, including any of bands 1-70 or other bands, as disclosed in ETSI TS136 104 V13.5.0 (2016-10).

In another configuration, the repeater 120 can improve the wireless connection between the wireless device 110 and the base station 130 (e.g., cell tower) or another type of wireless wide area network (WWAN) access point (AP) by amplifying desired signals relative to a noise floor. The repeater 120 can boost signals for cellular standards, such as the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) Release 8, 9, 10, 11, 12, 13, 14, 15, or 16 standards or Institute of Electronics and Electrical Engineers (IEEE) 802.16. In one configuration, the repeater 120 can boost signals for 3GPP LTE Release 16.2.0 (July 2019) or other desired releases.

The repeater 120 can boost signals from the 3GPP Technical Specification (TS) 36.101 (Release 16 Jul. 2019) bands or LTE frequency bands. For example, the repeater 120 can boost signals from the LTE frequency bands: 2, 4, 5, 12, 13, 17, 25, and 26. In addition, the repeater 120 can boost selected frequency bands based on the country or region in which the repeater is used, including any of bands 1-85 or other bands, as disclosed in 3GPP TS 36.104 V16.2.0 (July 2019), and depicted in Table 1:

For purposes of this application, a frequency band (e.g., band 12 (B12)) can refer to a 3GPP long term evolution (LTE) frequency band (e.g., 3GPP LTE Band 12) or a 3GPP fifth generation (5G) frequency band (e.g., 3GPP 5G band 12 (n12)).

The number of LTE frequency bands and the level of signal improvement can vary based on a particular wireless device, cellular node, or location. Additional domestic and international frequencies can also be included to offer increased functionality. Selected models of the signal booster 120 can be configured to operate with selected frequency bands based on the location of use. In another example, the signal booster 120 can automatically sense from the wireless device 110 or base station 130 (or GPS, etc.) which frequencies are used, which can be a benefit for international travelers.

In one example, the integrated device antenna 124 and the integrated node antenna 126 can be comprised of a single antenna, an antenna array, or have a telescoping form-factor. In another example, the integrated device antenna 124 and the integrated node antenna 126 can be a microchip antenna. An example of a microchip antenna is AMMAL001. In yet another example, the integrated device antenna 124 and the integrated node antenna 126 can be a printed circuit board (PCB) antenna. An example of a PCB antenna is TE 2118310-1.

In one example, the integrated device antenna 124 can receive uplink (UL) signals from the wireless device 110 and transmit DL signals to the wireless device 110 using a single antenna. Alternatively, the integrated device antenna 124 can receive UL signals from the wireless device 110 using a dedicated UL antenna, and the integrated device antenna 124 can transmit DL signals to the wireless device 110 using a dedicated DL antenna.

In one example, the integrated device antenna 124 can communicate with the wireless device 110 using near field communication. Alternatively, the integrated device antenna 124 can communicate with the wireless device 110 using far field communication.

In one example, the integrated node antenna 126 can receive downlink (DL) signals from the base station 130 and transmit uplink (UL) signals to the base station 130 via a single antenna. Alternatively, the integrated node antenna 126 can receive DL signals from the base station 130 using a dedicated DL antenna, and the integrated node antenna 126 can transmit UL signals to the base station 130 using a dedicated UL antenna.

In one configuration, multiple signal boosters can be used to amplify UL and DL signals. For example, a first signal booster can be used to amplify UL signals and a second signal booster can be used to amplify DL signals. In addition, different signal boosters can be used to amplify different frequency ranges.

In one configuration, the signal booster 120 can be configured to identify when the wireless device 110 receives a relatively strong downlink signal. An example of a strong downlink signal can be a downlink signal with a signal strength greater than approximately −80 dBm. The signal booster 120 can be configured to automatically turn off selected features, such as amplification, to conserve battery life. When the signal booster 120 senses that the wireless device 110 is receiving a relatively weak downlink signal, the integrated booster can be configured to provide amplification of the downlink signal. An example of a weak downlink signal can be a downlink signal with a signal strength less than −80 dBm.

In one example, the signal booster 120 can also include one or more of: a waterproof casing, a shock absorbent casing, a flip-cover, a wallet, or extra memory storage for the wireless device. In one example, extra memory storage can be achieved with a direct connection between the signal booster 120 and the wireless device 110. In another example, Near-Field Communications (NFC), Bluetooth v4.0, Bluetooth Low Energy, Bluetooth v4.1, Bluetooth v4.2, Bluetooth 5, Ultra High Frequency (UHF), 3GPP LTE, Institute of Electronics and Electrical Engineers (IEEE) 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, or IEEE 802.11ad can be used to couple the signal booster 120 with the wireless device 110 to enable data from the wireless device 110 to be communicated to and stored in the extra memory storage that is integrated in the signal booster 120. Alternatively, a connector can be used to connect the wireless device 110 to the extra memory storage.

In one example, the signal booster 120 can include photovoltaic cells or solar panels as a technique of charging the integrated battery and/or a battery of the wireless device 110. In another example, the signal booster 120 can be configured to communicate directly with other wireless devices with signal boosters. In one example, the integrated node antenna 126 can communicate over Very High Frequency (VHF) communications directly with integrated node antennas of other signal boosters. The signal booster 120 can be configured to communicate with the wireless device 110 through a direct connection, Near-Field Communications (NFC), Bluetooth v4.0, Bluetooth Low Energy, Bluetooth v4.1, Bluetooth v4.2, Ultra High Frequency (UHF), 3GPP LTE, Institute of Electronics and Electrical Engineers (IEEE) 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, IEEE 802.11ad, a TV White Space Band (TVWS), or any other industrial, scientific and medical (ISM) radio band. Examples of such ISM bands include 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, or 5.9 GHz. This configuration can allow data to pass at high rates between multiple wireless devices with signal boosters. This configuration can also allow users to send text messages, initiate phone calls, and engage in video communications between wireless devices with signal boosters. In one example, the integrated node antenna 126 can be configured to couple to the wireless device 110. In other words, communications between the integrated node antenna 126 and the wireless device 110 can bypass the integrated booster.

In another example, a separate VHF node antenna can be configured to communicate over VHF communications directly with separate VHF node antennas of other signal boosters. This configuration can allow the integrated node antenna 126 to be used for simultaneous cellular communications. The separate VHF node antenna can be configured to communicate with the wireless device 110 through a direct connection, Near-Field Communications (NFC), Bluetooth v4.0, Bluetooth Low Energy, Bluetooth v4.1, Bluetooth v4.2, Ultra High Frequency (UHF), 3GPP LTE, Institute of Electronics and Electrical Engineers (IEEE) 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11ac, IEEE 802.11ad, a TV White Space Band (TVWS), or any other industrial, scientific and medical (ISM) radio band.

In one configuration, the signal booster 120 can be configured for satellite communication. In one example, the integrated node antenna 126 can be configured to act as a satellite communication antenna. In another example, a separate node antenna can be used for satellite communications. The signal booster 120 can extend the range of coverage of the wireless device 110 configured for satellite communication. The integrated node antenna 126 can receive downlink signals from satellite communications for the wireless device 110. The signal booster 120 can filter and amplify the downlink signals from the satellite communication. In another example, during satellite communications, the wireless device 110 can be configured to couple to the signal booster 120 via a direct connection or an ISM radio band. Examples of such ISM bands include 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, or 5.9 GHz.

FIG. 2 illustrates exemplary frequency ranges for a plurality of uplink and downlink bands. The frequency ranges can be measured in megahertz (MHz). The uplink bands can include band 12 (B12), band 13 (B13) and band 14 (B14). The downlink bands can include band 12 (B12), band 13 (B13) and band 14 (B14). As shown, B12 can correspond to a frequency range of 699 MHz to 716 MHz in an uplink. B12 can correspond to a frequency range of 729 MHz to 746 MHz in a downlink, B13 can correspond to a frequency range of 746 MHz to 756 MHz in the downlink, and B14 can correspond to a frequency range of 758 MHz to 768 MHz in the downlink. B12, B13 and B14 can be spectrally adjacent bands in the downlink.

In addition, B13 can correspond to a frequency range of 777 MHz to 787 MHz in the uplink, and B14 can correspond to a frequency range of 788 MHz to 798 MHz in the uplink. B13 and B14 can be spectrally adjacent bands in the downlink.

FIG. 3 illustrates an exemplary signal booster 300. The signal booster 300 can include one or more uplink signal paths for selected bands, and the signal booster 300 can include one or more downlink signal paths for selected bands. The uplink signal paths can include one or more amplifiers and band pass filters to amplify uplink signals. Similarly, the downlink signal paths can include one or more amplifiers and band pass filters to amplify downlink signals.

In the example shown in FIG. 3, the signal booster 300 can have a first uplink signal path 330 for band 12 (B12) and a second uplink signal path 340 for B13 and B14. In uplink, B12 corresponds to a frequency range of 699 megahertz (MHz) to 716 MHz, B13 corresponds to a frequency range of 777 MHz to 787 MHz, and B14 corresponds to a frequency range of 788 MHz to 798 MHz. In the uplink, B13 and B14 can be spectrally adjacent bands. In addition, in this example, the signal booster 300 can have a downlink signal path 350 for B12, B13 and B14. In other words, the downlink signal path 350 can be a combined downlink signal path for B12, B13 and B14. In downlink, B12 corresponds to a frequency range of 729 MHz to 746 MHz, B13 corresponds to a frequency range of 746 MHz to 756 MHz, and B14 corresponds to a frequency range of 758 MHz to 768 MHz. In the downlink, B12, B13 and B14 are all spectrally adjacent to each other. Even though there is a 2 MHz gap between an end of B13 DL and a start of B14 DL (e.g., 756 MHz and 758 MHz), B13 DL and B14 DL can be considered spectrally adjacent to each other since an RF filter may be unable to roll-off quickly enough to separate the two bands.

In another example, B12 uplink, including a frequency range of 699 MHz to 716 MHz and B12 DL, including a frequency range of 729 MHz to 746 MHz may not be spectrally adjacent to each other because filters (e.g., SAW filters, BAW filters, FBAR filters, ceramic filters, and the like) can adequately isolate the frequency range of B12 UL and the frequency range of B12 DL. SAW filter, BAW filters, FBAR filters, ceramic filters, and the like can be configured to have a roll off steep enough to separately filter the two bands due to the frequency gap of 13 MHz between 716 MHz and 729 MHz.

In another example, two signals can be considered to be spectrally adjacent when standard filters (e.g., SAW filters, BAW filters, FBAR filters, ceramic filters, or the like) cannot be configured to adequately isolate the two signals resulting in interference between the two signals. Two signals are considered to be spectrally adjacent when the relative gap between the signals is not sufficient to allow the filters to isolate the two signals. Two passbands can have a gap between their respective passbands. A gap can be between a first edge of a passband of a first filter and a second edge of a passband of a second filter. For example, a first passband can be from 663 MHz to 698 MHz. A second passband can be from 701 MHz to 726 MHz. The gap is 3 MHz between the 698 MHz edge of the first passband and the 701 MHz edge of the second passband. A relative gap can be the gap between the passbands relative to a center frequency of the gap and can be a percentage calculated from a ratio of a gap in MHz and a center frequency of the gap in MHz. In one example, a 3 MHz gap at a center frequency of the gap of about 699.5 MHz can have a relative gap of about 0.4%. In one example, a SAW filter cannot be configured to have a roll off steep enough to separately filter two bands with a relative gap of less than 0.7%. In another example, a SAW filter can have a roll off steep enough to separately filter two bands with a relative gap of more than 2.0%. In another example, two signals can be considered to be spectrally adjacent with a relative gap of less than about 2.0%, 1.65%, 1.35%, 1.0%, 0.70%, or 0.50%. As used herein, the term “gap” with guard band, although a gap does not have to be a guard band.

In one example, the signal booster 300 can receive uplink signals from a mobile device (not shown) via an inside antenna coupled to the signal booster 300. An uplink signal can pass through a first triplexer 310 (or first multiband filter), and then the uplink signal can be provided to the first uplink signal path 330 for B12 or the second uplink signal path 340 for B13 and B14. The first and second uplink signal paths 330, 340 can perform amplification and filtering of the uplink signal. The first and second uplink signal paths 330, 340 can each include a low noise amplifier (LNA) and a power amplifier (PA). The uplink signal can be provided to a second triplexer 320 (or second multiband filter), and then the uplink signal can be provided to a base station (not shown) via an outside antenna coupled to the signal booster 300.

In another example, the signal booster 300 can receive downlink signals from the base station via the outside antenna. A downlink signal can pass through the second triplexer 320 (or second multiband filter), and then the downlink signal can be provided to the combined downlink signal path 350 for B12, B13 and B14. The combined downlink signal path 350 can perform amplification and filtering of the downlink signal. The combined downlink signal path 350 can include a low noise amplifier (LNA) and a power amplifier (PA). The downlink signal can be provided to the first triplexer 310 (or first multiband filter), and then the downlink signal can be provided to the mobile device via the inside antenna.

In one configuration, the signal booster 300 can include a controller 360. Generally speaking, the controller 360 can be configured to perform network protection for the signal booster 300. The controller 360 can perform network protection in accordance with Part 20 of the Federal Communications Commission (FCC) Consumer Booster Rules. The FCC Consumer Booster Rules necessitate that uplink signal paths and downlink signal are to work together for network protection. Network protection can be performed in order to protect a cellular network from overload or noise floor increase. The controller 360 can perform network protection by adjusting a gain or noise power for each band in the uplink transmission paths 330, 340 based on control information from each band in the downlink transmission paths 350. The control information from each band in the downlink transmission paths 350 can include a received signal strength indication (RSSI) associated with downlink received signals. In other words, based on the RSSI of the downlink received signals traveling on the downlink transmission paths 350, the controller 360 can adjust (i.e., increase or decrease) the gain or noise power for the uplink transmission paths 330, 340. By adjusting the gain or noise floor when performing the network protection, the signal booster 300 can prevent the network (e.g., base stations) from becoming overloaded with uplink signals from the signal booster 300 that exceed a defined threshold.

In the example shown in FIG. 3, the controller 360 can separately detect control information (e.g., RSSI) for downlink received signals with respect to B12, B13 and B14. In other words, the signal booster 300 can detect control information that pertains only to downlink received signals for B12, the signal booster 300 can detect control information that pertains only to downlink received signals for B13, and the signal booster 300 can detect control information that pertains only to downlink received signals for B14. The controller 360 can adjust the uplink gain or noise floor for B12 (i.e., the first uplink signal path 330) based only on the control information for the downlink received signals on B12. The controller 360 can adjust the uplink gain or noise floor for B13 and B14 (i.e., the second uplink signal path 340) based only on the control information for the downlink received signals on B13 or B14. In other words, the uplink gain or noise power for B12 (i.e., the first uplink signal path 330) can be controlled independent of the uplink gain or noise power for B13 and B14 (i.e., the second uplink signal path 340).

More specifically, as shown in FIG. 3, the signal booster 300 can include a switchable B12 downlink band pass filter, a switchable B13 downlink bandpass filter, a switchable B14 downlink bandpass filter, and a signal detector. The signal detector can be communicatively coupled to the switchable B12 downlink band pass filter, the switchable B13 downlink band pass filter and the switchable B14 downlink band pass filter. The B12, B13 and B14 downlink bandpass filters can be switched in and out, such that downlink received signals for B12, B13 or B14 can be provided to the signal detector. The signal detector can be a log detector (e.g., a diode), and the signal detector can detect the control information (e.g., RSSI) associated with the downlink received signals for B12, B13 or B14. In other words, the switchable B12, B13 and B14 downlink band pass filters can enable the signal detector to separately detect the control information for downlink received signals for B12, B13 and B14. The signal detector can provide the control information to the controller 360. Based only on the control information for downlink received signals for B12, the controller 360 can adjust the uplink gain or noise floor for B12 (i.e., the first uplink signal path 330). Similarly, based only on the control information for downlink received signals for B13 or B14, the controller 360 can adjust the uplink gain or noise floor for B13 and B14 (i.e., the second uplink signal path 340).

In general, using the signal detector, the controller 360 can detect single downlink bands while multiple downlink bands are passing through a common downlink signal path. With respect to the specific example shown in FIG. 3, the controller 360 can perform independent detection of control information for B12, B13 and B14, even though the signal booster 300 has a combined downlink signal path for B12, B13 and B14.

In an alternative configuration, the signal booster 300 can include a first signal detector, a second signal detector and a third signal detector. The first signal detector can detect control information (e.g., RSSI) associated with a received downlink signal for B12. The second signal detector can detect control information (e.g., RSSI) associated with a received downlink signal for B13. The third signal detector can detect control information (e.g., RSSI) associated with a received downlink signal for B14. Therefore, in this configuration, separate signal detectors can be utilized to detect the control information for the multiple downlink bands.

In one configuration, the downlink signal path 350 can include a pass through signal path to the signal detector. The pass through signal path can bypass the switchable B12, B13 and B14 downlink band pass filters. The signal detector can measure a signal power level for the pass through signal path. The signal power level can be utilized to perform automatic gain control (AGC) and to maintain a linearity of a downlink signal. Alternatively, a signal power level for each of the switchable B12, B13 and B14 downlink band pass filters can be measured and added to calculate a total signal power level.

In one configuration, the first triplexer 310 can include a first common port communicatively coupled to the inside antenna. The first triplexer 310 can include a first port that is communicatively coupled to the first uplink signal path 330 for B12. The first triplexer 310 can include a second port that is communicatively coupled to the second uplink signal path 340 for B13 and B14. The first triplexer 310 can include a third port that is communicatively coupled to the combined downlink signal path 350 for B12, B13 and B14. Similarly, the second triplexer 320 can include a second common port communicatively coupled to the outside antenna. The second triplexer 320 can include a first port that is communicatively coupled to the first uplink signal path 330 for B12. The second triplexer 320 can include a second port that is communicatively coupled to the second uplink signal path 340 for B13 and B14. The second triplexer 320 can include a third port that is communicatively coupled to the combined downlink signal path 350 for B12, B13 and B14.

In one configuration, the first triplexer 310 and the second triplexer 320 can include separate filters for B12 UL, B13 UL and/or B14 UL. Similarly, the first triplexer 310 and the second triplexer 320 can include separate filters for B12 DL, B13 DL and/or B14 DL. The filters can filter UL or DL signals, respectively.

In one configuration, the signal booster 300 can include a first multiband filter and a second multiband filter. The first and second multiband filters can be single-input single-output (SISO) multiband filters or double-input single-output (DISO) multiband filters. In this configuration, the first multiband filter and the second multiband filter can replace the first triplexer 310 and the second triplexer 320, respectively. The first multiband filter can include a first uplink port and a first downlink port. The second multiband filter can include a second uplink port and a second downlink port. One or more uplink signal paths 330, 340 can be communicatively coupled between the first uplink port in the first multiband filter and the second uplink port in the second multiband filter. Similarly, one or more downlink signal paths 350 can be communicatively coupled between the first downlink port in the first multiband filter and the second downlink port in the second multiband filter. In this configuration, each of the first and second multiband filters can include a single downlink port and a single uplink port.

A signal detector can also be used to detect the first, second, or third downlink bands using switchable bandpass filters to pass selected bands to the signal detector. In one configuration, the downlink signal path can include a pass through signal path to the signal detector.

The cellular signal booster 600 can include a controller 640 operable to perform network protection by adjusting an uplink gain or noise power for a first uplink band in a first uplink cellular signal path, or for a second uplink band and a third uplink band in a second uplink cellular signal path. The second uplink band can be spectrally adjacent to the third uplink band, and the uplink gain or noise power can be adjusted in the first uplink cellular path or the second uplink cellular path using control information associated with the downlink cellular signal received in one or more of the first downlink band, the second downlink band or the third downlink band.

FIG. 9 illustrates an exemplary signal booster 900. The signal booster 900 can include a first multiband filter 910 that includes a first first-direction port and a first second-direction port. The signal booster 900 can include a second multiband filter 920 that includes a second first-direction port and a second second-direction port.

FIG. 10 illustrates an exemplary signal booster 1000 that includes uplink and/or downlink signal paths in spectrally adjacent bands. The signal booster 1000 can include a first multiband filter 1010 and a second multiband filter 1020. The first multiband filter 1010 can be communicatively coupled to an inside antenna and the second multiband filter 1020 can be communicatively coupled to an outside antenna. The signal booster 1000 can include a first uplink signal path 1030 and a second uplink signal path 1040 communicatively coupled between the first multiband filter 1010 and the second multiband filter 1020. The first uplink signal path 1030 and the second uplink signal path 1040 can each include one or more amplifiers and one or more band pass filters. Similarly, the signal booster 1000 can include a first downlink signal path 1050 and a second downlink signal path 1060 communicatively coupled between the first multiband filter 1010 and the second multiband filter 1020. The first downlink signal path 1050 and the second downlink signal path 1060 can each include one or more amplifiers and one or more band pass filters. Each signal path (downlink and uplink) can include a signal detector to detect control information associated with signals transmitted on the signal path. In addition, the signal booster 900 can employ down-converting, and then either an analog intermediate frequency (IF) filter or digital filter.

In this example, the first uplink signal path 1030 can be for band 12 (B12) and the 600 MHz uplink frequency range. In other words, the first uplink signal path 1030 can be a combined signal path for B12 and 600 MHz. In uplink, B12 corresponds to a frequency range of 699 megahertz (MHz) to 716 MHz, so B12 and the 600 MHz frequency range are spectrally adjacent. In this example, the second uplink signal path 1040 can be for B12. In uplink, B13 corresponds to a frequency range of 777 MHz to 787 MHz. In this example, the first downlink signal path 1050 can be for B12 and B13. In other words, the first downlink signal path 1050 can be a combined signal path for B12 and B13. In downlink, B12 corresponds to a frequency range of 729 MHz to 746 MHz and B13 corresponds to a frequency range of 746 MHz to 756 MHz, so B12 and B13 are spectrally adjacent to each other in the downlink. Alternatively, the first downlink signal path 1050 can be a combined signal path for B12, B13 and B14, which are all spectrally adjacent to each other in the downlink. In this example, the second downlink signal path 1060 can be for the 600 MHz downlink frequency range.

In an alternative configuration, first uplink signal path 1030 can be for B12 and the 600 MHz uplink frequency range, and the second uplink signal path 1040 can be for B13 and a band 14 (B14). In uplink, B14 corresponds to a frequency range of 788 MHz to 798 MHz. In addition, the first downlink signal path 1050 can be for B12, B13 and B14, and the second downlink signal path 1060 can be for the 600 MHz downlink frequency range. In downlink B14 corresponds to a frequency range of 758 MHz to 768 MHz.

FIG. 11 exemplary frequency ranges for a 600 megahertz (MHz) frequency band. As shown, a band 12 (B12) uplink (UL) band corresponds to a frequency range of 699 MHz to 716 MHz. A 600 MHz UL band can be spectrally adjacent to the B12 UL band. The 600 MHz UL band can range from a defined frequency range (e.g., 6XX MHz to 6XX MHz). A 600 MHz downlink (DL) band can have a lower frequency than the 600 MHz UL band, and the 600 MHz DL band and the 600 MHz UL band can be separated by a guard band (GB). The 600 MHz DL band can range from a defined frequency range (e.g., 6XX MHz to 6XX MHz). In addition, a radio astronomy service (RAS) can correspond to a frequency range of 608 MHz to 614 MHz. In one example, 84 MHz of the 600 MHz frequency band can be utilized for uplink and downlink traffic. Therefore, 7 paired blocks and the RAS may not be utilized for uplink and downlink traffic in the 600 MHz frequency band.

FIG. 12 illustrates an exemplary signal booster 1200 that includes uplink and/or downlink signal paths in spectrally adjacent bands. The signal booster 1200 can include a first multiband filter 1210 (e.g., a first triplexer) and a second multiband filter 1220 (e.g., a second triplexer). The first multiband filter 1210 can be communicatively coupled to an inside antenna and the second multiband filter 1220 can be communicatively coupled to an outside antenna. The signal booster 1200 can include a first uplink signal path 1230 and a second uplink signal path 1240 communicatively coupled between the first multiband filter 1210 and the second multiband filter 1220. The first uplink signal path 1230 and the second uplink signal path 1240 can each include one or more amplifiers and one or more band pass filters. In addition, the signal booster 1200 can include a combined downlink signal path 1250 communicatively coupled between the first multiband filter 1210 and the second multiband filter 1220. The combined downlink signal path 1250 can include one or more amplifiers and one or more band pass filters.

In this example, the first uplink signal path 1230 can be for B12 and the second uplink signal path 1240 can be for B13. In this example, the combined downlink signal path 1250 can be for B12 and B13.

In one example, the combined downlink signal path 1250 can include a switchable B12 downlink band pass filter, a switchable B13 downlink bandpass filter, a switchable B12/B13 downlink bandpass filter, and a signal detector. The signal detector can be communicatively coupled to the switchable B12 downlink band pass filter, the switchable B13 downlink band pass filter and the switchable B12/B13 downlink band pass filter. The B12, B13 and B12/B13 downlink bandpass filters can be switched in and out, such that downlink received signals for B12, B13 or B12/B13 can be provided to the signal detector. The signal detector can be a log detector (e.g., a diode), and the signal detector can detect the control information (e.g., RSSI) associated with the downlink received signals for B12, B13 or B12/B13. In other words, the switchable B12, B13 and B12/B13 downlink band pass filters can enable the signal detector to separately detect the control information for downlink received signals for B12, B13 and B12/B13.

In one example, the signal booster 1200 can operate in a wideband mode or a single-band mode (e.g., only one of B12 or B13). For example, to initiate a single-band mode, a selected uplink power amplifier (PA) can be turned off and a selected downlink bandpass filter (BPF) can be switched on. As a specific example, a B13 UL PA can be turned off and a B12 DL BPF can be switched on. For the wideband mode, a wideband BPF for downlink can be switched in and both UL Pas can be turned off.

FIG. 13 illustrates an exemplary signal booster 1300 that includes uplink and/or downlink signal paths in spectrally adjacent bands. The signal booster 1300 can include a first multiband filter 1310 (e.g., a first triplexer) and a second multiband filter 1320 (e.g., a second triplexer). The first multiband filter 1310 can be communicatively coupled to an inside antenna and the second multiband filter 1320 can be communicatively coupled to an outside antenna. The signal booster 1300 can include a first uplink signal path 1330 and a second uplink signal path 1340 communicatively coupled between the first multiband filter 1310 and the second multiband filter 1320. The first uplink signal path 1330 and the second uplink signal path 1340 can each include one or more amplifiers and one or more band pass filters. In addition, the signal booster 1300 can include a combined downlink signal path 1350 communicatively coupled between the first multiband filter 1310 and the second multiband filter 1320. The combined downlink signal path 1350 can include one or more amplifiers and one or more band pass filters.

In this example, the first uplink signal path 1330 can be for B12 and B17 and the second uplink signal path 1340 can be for B13. In the uplink, B12 corresponds to a frequency range of 699 MHz to 716 MHz and B17 corresponds to a frequency range of 704 MHz to 716 MHz. In this example, the combined downlink signal path 1350 can be for B12 and B13 and B17. In downlink, B12 corresponds to a frequency range of 729 MHz to 746 MHz, B13 corresponds to a frequency range of 746 MHz to 756 MHz and B17 corresponds to a frequency range of 734 to 746 MHz. Therefore, the signal booster 1300 can operate in a B12/B13 mode or a B17/B13 mode.

In one example, the first uplink signal path 1330 can include a switchable B12 uplink band pass filter and a switchable B17 uplink bandpass filter. In another example, the combined downlink signal path 750 can include a switchable B12/B13 downlink band pass filter, a switchable B17/B13 downlink bandpass filter, and a signal detector. The signal detector can be communicatively coupled to the switchable B12/B13 downlink band pass filter and the switchable B17/B13 downlink band pass filter. The B12/B13 and B17/B13 downlink bandpass filters can be switched in and out, such that downlink received signals for B12/B13 or B17/B13 can be provided to the signal detector. The signal detector can be a log detector (e.g., a diode), and the signal detector can detect the control information (e.g., RSSI) associated with the downlink received signals for B12/B13 or B17/B13. In other words, the switchable B12/B13 and B17/B13 downlink band pass filters can enable the signal detector to separately detect the control information for downlink received signals for B12/B13 and B17/B13.

In one configuration, the first uplink signal path 1330 and the second uplink signal path 1340 can be controlled independently of the combined downlink signal path 1350, which can provide additional flexibility in network protections and mitigate near-far problems.

FIG. 14 illustrates an exemplary signal booster that is operable in a wideband mode or a channelized mode. The signal booster 1400 can include a first multiband filter 1410 (e.g., a first triplexer) and a second multiband filter 1420 (e.g., a second triplexer). The first multiband filter 1410 can be communicatively coupled to an inside antenna and the second multiband filter 1420 can be communicatively coupled to an outside antenna. The signal booster 1400 can include a first uplink signal path 1430 and a second uplink signal path 1440 communicatively coupled between the first multiband filter 1410 and the second multiband filter 1420. The first uplink signal path 1430 and the second uplink signal path 1440 can each include one or more amplifiers and one or more band pass filters. In addition, the signal booster 1400 can include a combined downlink signal path 1450 communicatively coupled between the first multiband filter 1410 and the second multiband filter 1420. The combined downlink signal path 1450 can include one or more amplifiers and one or more band pass filters.

In this example, the first uplink signal path 1430 can be for B12 and the second uplink signal path 1440 can be for B13. In this example, the combined downlink signal path 1450 can be for B12 and B13.

In one example, the first uplink signal path 1430 can include a switchable B12 uplink band pass filter and a switchable B12 uplink channelized bandpass filter. The switchable B12 uplink band pass filter can be a wideband B12 uplink filter (i.e., a wideband filter that passes signals in the entire B12 uplink band), whereas the switchable B12 uplink channelized bandpass filter can be a channelized B12 uplink filter (i.e., a channelized filter that only passes signals in a portion of the B12 uplink band). Similarly, the second uplink signal path 1440 can include a switchable B13 uplink band pass filter and a switchable B13 uplink channelized bandpass filter.

In one example, the combined downlink signal path 1450 can include a switchable B12/B13 downlink band pass filter (i.e., a wideband filter that passes signals in the entire B12/B13 downlink band), a switchable B12 downlink channelized bandpass filter (a channelized filter that only passes signals in a portion of the B12 downlink band), and a B13 downlink channelized bandpass filter (a channelized filter that only passes signals in a portion of the B13 downlink band). The combined downlink signal path 1450 can include a splitter that provides signals to the switchable B12/B13 downlink band pass filter or the switchable B12 downlink channelized bandpass filter, or to the B13 downlink channelized bandpass filter. In addition, the combined downlink signal path 1450 can include signal detector(s) that detect control information (e.g., RSSI) associated with the downlink received signals for B12/B13, a channelized B12 or a channelized B13, respectively.

In one example, the signal booster 1400 can operate in a wideband mode or a parallel channelized mode, in which B12 UL and B13 UL can be adjusted separately. In the wideband mode, a wideband BPF for UL and DL can be switched in (i.e., the B12 UL BPF, the B13 UL BPF and the B12/13 DL BPF can be switched in), and in the DL, a B13 DL channelized BPF can be disabled. In the parallel channelized mode, a channelized BPF for UL and DL can be switched in (i.e., the B12 UL channelized BPF, the B13 UL channelized BPF, and the B12 DL channelized BPF can be switched in, and in the DL, the B13 DL channelized BPF can be enabled. In another example, B12 and B13 in the uplink can be wideband, and the B12 or B13 BPFs can be switched between each other in the downlink, which can result in the passed band being full but blocks the other band.

FIG. 15 illustrates an exemplary signal booster that is operable in a wideband mode or a channelized mode. The signal booster 1500 can include a first multiband filter 1510 (e.g., a first duplexer) and a second multiband filter 1520 (e.g., a second duplexer). The first multiband filter 1510 can be communicatively coupled to an inside antenna and the second multiband filter 1520 can be communicatively coupled to an outside antenna. The signal booster 1500 can include an uplink signal path 1530 and a downlink signal path 1540 communicatively coupled between the first multiband filter 1510 and the second multiband filter 1520. The uplink signal path 1530 and the downlink signal path 1540 can each include one or more amplifiers and one or more band pass filters.

In this example, the uplink signal path 1530 can be for B5 and the downlink signal path 1540 can be for B5. In the uplink, B5 corresponds to a frequency range of 824 MHz to 849 MHz, and in the downlink, B5 corresponds to a frequency range of 869 MHz to 894 MHz.

In one example, the uplink signal path 1530 can include a switchable B5 uplink band pass filter (i.e., a wideband filter that passes signals in the entire B5 uplink band), a switchable B5 uplink channelized bandpass filter (a channelized filter that only passes signals in a first portion of the B5 uplink band, which corresponds to Channel A), and a B5 uplink channelized bandpass filter (a channelized filter that only passes signals in a first second of the B5 uplink band, which corresponds to Channel B). The uplink signal path 1530 can include a splitter that provides signals to the switchable B5 uplink band pass filter or the switchable B5 uplink channelized bandpass filter corresponding to Channel A, or to the B5 uplink channelized bandpass filter corresponding to Channel B.

In one example, the downlink signal path 1540 can include a switchable B5 downlink band pass filter (i.e., a wideband filter that passes signals in the entire B5 downlink band), a switchable B5 downlink channelized bandpass filter (a channelized filter that only passes signals in a first portion of the B5 downlink band, which corresponds to Channel A), and a B5 downlink channelized bandpass filter (a channelized filter that only passes signals in a first second of the B5 downlink band, which corresponds to Channel B). The downlink signal path 1540 can include a splitter that provides signals to the switchable B5 downlink band pass filter or the switchable B5 downlink channelized bandpass filter corresponding to Channel A, or to the B5 downlink channelized bandpass filter corresponding to Channel B. In addition, the downlink signal path 1540 can include signal detector(s) that detect control information (e.g., RSSI) associated with the downlink received signals for Channel A of B5 or Channel B of B5, respectively.

In one example, the signal booster 1500 can operate in a wideband mode (full B5) or a parallel channelized mode, in which Channel A of B5 and Channel B of B5 in the uplink can be adjusted separately. In the wideband mode, a wideband BPF for UL and DL can be switched in (i.e., the B5 UL BPF and the B5 DL BPF), and B5 Channel B BPFs for UL and DL can be disabled. In the parallel channelized mode, B5 Channel A BPFs for UL and DL can be switched in (i.e., the B5 UL Channel A BPF and the B5 DL Channel A BPF can be switched in), and the B5 Channel B BPFs for UL and DL can be enabled (i.e., the B5 UL Channel B BPF and the B5 DL Channel B BPF can be enabled). In another example, single pole double throw (SPDT) switches can be utilized to maintain impedance matching to splitter(s) in the uplink signal path 1530 and/or the downlink signal path 1540 when any of Enable #1-4 are disabled.

Various techniques, or certain aspects or portions thereof, can take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, compact disc-read-only memory (CD-ROMs), hard drives, non-transitory computer readable storage medium, or any other machine-readable storage medium wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the various techniques. Circuitry can include hardware, firmware, program code, executable code, computer instructions, and/or software. A non-transitory computer readable storage medium can be a computer readable storage medium that does not include signal. In the case of program code execution on programmable computers, the computing device can include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. The volatile and non-volatile memory and/or storage elements can be a random-access memory (RAM), erasable programmable read only memory (EPROM), flash drive, optical drive, magnetic hard drive, solid state drive, or other medium for storing electronic data. One or more programs that can implement or utilize the various techniques described herein can use an application programming interface (API), reusable controls, and the like. Such programs can be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) can be implemented in assembly or machine language, if desired. In any case, the language can be a compiled or interpreted language, and combined with hardware implementations.

As used herein, the term processor can include general purpose processors, specialized processors such as VLSI, FPGAs, or other types of specialized processors, as well as base band processors used in transceivers to send, receive, and process wireless communications.

It should be understood that many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module can be implemented as a hardware circuit comprising custom very-large-scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module can also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

In one example, multiple hardware circuits or multiple processors can be used to implement the functional units described in this specification. For example, a first hardware circuit or a first processor can be used to perform processing operations and a second hardware circuit or a second processor (e.g., a transceiver or a baseband processor) can be used to communicate with other entities. The first hardware circuit and the second hardware circuit can be incorporated into a single hardware circuit, or alternatively, the first hardware circuit and the second hardware circuit can be separate hardware circuits.

Modules can also be implemented in software for execution by various types of processors. An identified module of executable code can, for instance, comprise one or more physical or logical blocks of computer instructions, which can, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but can comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module of executable code can be a single instruction, or many instructions, and can even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data can be identified and illustrated herein within modules, and can be embodied in any suitable form and organized within any suitable type of data structure. The operational data can be collected as a single data set, or can be distributed over different locations including over different storage devices, and can exist, at least partially, merely as electronic signals on a system or network. The modules can be passive or active, including agents operable to perform desired functions.
